Google (GOOG+2.5%) and Samsung (SSNLF.PK) will use Google I/O to show off a version of the Galaxy S4 that (like Google's Nexus hardware) runs a stock version of Android, Geek.com reports. Google, which has cracked $900 for the first time today, has been working hard to promote stock Android relative to versions with custom skins such as Samsung's TouchWiz and HTC's Sense, but with limited success. Upcoming Motorola phones will reportedly run stock Android. I/O festivities start at 12PM ET (live blog). (music service reports)
